LIGHTNING-CONDUCTOR.

:PECIFICATIGN forming part of Letters Patent NO. 311,115, dated January 20, 1885.

(No model.)

To ar/ZZ whom, it may 0071.067111.:

Be it known that I, JosEPH R. FEICKE, a citizen of the United States, living in the city of Pittsburg, county ol' Allegheny, and State of Pennsylvania, have invented a new and useful Improvement in LightningeConductoi-s; and I do declare the following to be a full, clear, and exact description of the saine, such as will enableany person skilled in the art or science to which it apperiains most nearly to make, construct, and use the same.

My invention relates to an improvement in lightning-conductors; and it consists in a solid rod the point of which is attached toits upper end, a connecting-tube, and cable or conductor which is connected to the solid rod by the tube, as will be more fully described hereinafter.

The object of my invention is to provide a stiff support for the point of a flexible wirecable lightning-conductor, so that the upper end of the conductor can be carried any desired distance above the top of the house.

Figure lis a side elevation, partly in section, of aconductor embodyingmyinvention. Fig. 2 is a side elevation of the rod alone. Fig. 3 is a Vertical section of the connectingtube alone. Fig. 4 is a detached view of the cable.

. Fig. 5 is a perspective of the point and its at tachments.

G represents a cable conductor, which is preferably formed of copper wires, and which is flexible. Passed down over the top of this cable is the connecting-tube B, also preferably made of copper, and which will be of a length proportioned to the distance thepoint is to be raised above the top of the house.

In the top of the tube B is placed the solid copper rod A, which has its upper end, E, made screw-threaded, so as to receive the tip D. This rod A serves to brace the pipe or tube B, to make connection with the cable, and to support the tip. The screw-threaded end of the rod A projects just i'ar enough above the pipe or tube to allow the base of the tip to rest ou the top of the tube, and thus forni a neat finish and a continuous conducting-surface. The cable being iiexible, it becomes necessary to attach to it a rigid support for the tip, so as to keep the tip in a vertical position.

Having thus described my invention, I claiinl. A iiexible lightning conductor, G, in combination with the tube B, applied to its upper end. the tip D, applied at the upper end oi' the tube, and the rod A, supporting said tip, substantially as shown.

2. The combination of the cable conductor, a tube applied to its upper end, the rigid rod, which is placed in the tube, and the tip, substantially as set forth.

JOSEPH It. FRIOKE.
